Note that it's possible to connect a home-power jack even in a docking sled, so these are not mutually exclusive states.

I was looking in the FAQ and I don't understand if you can actually use the AC power while in a docking sled, or only make it think it's on AC power.
So is it possible to use AC power in the docking sled, or do I need to get a DC voltage supply of some sort if I build a home docking station? Thanks...
